Non-contact drying solution

Thanks to our subsidiaries M.D.S. and IR.D.S., ABK offers to customers a full range of coat drying solutions from the traditional dryers chromium plated going to the most modern air-turn I-Turn™ , from the gas fired IR IDry™ banks to one side or tunnel AIR FOIL DRYERS. The final member of the family being a compound air/IR dryer.

I-TURN™

It is a contact-free device which allows the web transfer from size/film press to post drying section avoiding any contact with metallic surfaces till the coat/starch is dry enough to be non-stick on conventional dryer cylinders.
The unique features of the “ITurn™” unit permit:

  • Control of the excess of ambient air which is carried at the inlet and outlet by the sheet by special adjustable anti-overspill nozzles,
  • Minimizing of sheet fluttering, air spillage and air consumption by optimized design of nozzles, slots and air bars

INFRARED UNITS


 

The IDRY unit special features lies in the design of the InfraRay™ emitters and reflects expertise and knowledge gathered over many years of infrared experience in the Pulp and Paper industry as well as months of R&D, computer modeling and systems testing.

The primary radiating surface reaches a more uniform and far higher operating temperature than emitters without screens, as a result emitter efficiency is higher.

The screen protects the radiating surface against coating splashes and other contamination that can reduce emitter lifetime. Moreover, these emitters fit as replacement in existing Gas-IR systems, regardless of the original manufacturer. Kit design including replaceable screen cut your operation and maintenance costs.

AIRFOIL DRYERS


 

In replacement or in addition to IR dryers, non-contact Airfoil dryer tunnels can be installed on machine after a film press to dry the size. They are also found in OMC lines after or instead of the IR unit in between two coating stations.

The air dryer takes the sheet in sandwich between two hot air cushions. A set of profiled aluminium nozzles blow the air regularly on to the sheet in both MD and CD, and is then sucked between 2 successive nozzles.
M.D.S. Airfoils can be made with a linear or “U-shaped” geometry and, according to the paper need have integrated infrared banks (compound airfoil series).
